G. M. PLUMB, OF NORTH ORANGE, NEW JERSEY.

TIME-TABLE FOR RAILROADS, &c.

Specification of Letters Patent No. 27,152, dated February 14, 1860.

To all whom it may concern:

Be it known that I, C. M. PLUME, of North Orange, in the county of Essexand State of New Jersey, have invented a new and useful Time-Table for Railway-Stations and for other Purposes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a :trent elevation ot my improved time-table to be used at railroad stations as a directory showing the time ot departure ot the trains. Fig. 2 is a vertical transverse section taken through Fig. l, as indicated by the red line m m marked thereon. Fig. 3 shows one ot the movable plates detached from the table frame.

Similar letters of reference indicate corresponding parts In the three figures.

The object of this invention is to obtain a cheap and ready reterence timetable for rail-road stations for giving information to ersons traveling over certain routes and to serve as a perpetual rail-road directory, showing the time of departure of the trains and the character of the trains leaving the station during the day or night.

The table is to be made so that malicious persons cannot injure or detace it by tampering with it, and so that the numerals or letters used upon it may be taken out with very little trouble and others inserted in their places. The whole device is to be made light, neat, and portable and may be hung out of reach or nailed up on the inside of the cars, in the house or out of doors.

To enable those skilled in the art to Jfully understand my invention I will proceed to describe its construction and operation.

In the drawings A, represents a frame which may be made of either sheet or cast metal or of wood, and of any desirable shape or size having a heading B of any suitable design upon which is printed the character of the table and any suitable directions which are to remain permanent. The shape of the trame shown by the drawings will answer all purposes and this has a central piece A, extending from its head to the foot piece which forms a part of the frame and serves to support one of the ends ot slide pieces C, whl e the side strips support the pposite ends of the slides. The outer edge o the side strips are turned over and bent so as to form grooves and the central strip A', has two grooves on its back side opening in opposite directions and continued from the bottom or toot strip to the inner edge of the heading B. These grooves are made so as to receive metal slides C, Fig. 3, and retain them in their pro er places. Each slide consists of a strip o metal, the length of the distance between the grooves on the central strip, and the groove on the side strips of the frame A, A', with the edges turned over so as to form grooves for receiving and holding fiat metal strips D. The lower corners of the slides G, have pro jecting portions a, a, of the same length throughout the series, which, when the slides are all in their proper places, in the frame, rest upon the top of each lower slide and keep them separated some quarter or half inch as shown by Fig. 1.

The topmost slides or those indicating the direction of the trains leaving the station may have each a single plate D, but the slides indicating the character of the trains going in a certain direction must contain separate plates c, d upon which are letters, numerals, or other signs, which can be renewed separately, and others inserted in their places as occasion requires. These small plates c, d, can be set up in the slides, there being as many characters or signs as there are changes to be made-like a printer would set up his types in his stick.

Then the characters have all been set up in the slides they are placed in the frame, by sliding them in from the top as shown by Fig. l, and can if necessary be locked up: the frame may now be hung up in any suitable place and it will serve as a perpetual t'me table for rail-road stations.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- 'Ihe within described construction of frame and movable slides with the separate movable plates with letters or numerals denoted thereon the whole being combined arranged and operating for the purposes and in the manner herein described.

C. PLUME.
